Who It's Built For
The armrest that finishes the chair. You're either configuring your first Vyper chair right now and wondering if armrests are worth it, or you've been using your Vyper for a while and your forearms have been hanging dead at your sides through every bench session. Either way, the answer is the same. Armrests change how the chair feels at hour three, hour five, hour eight. They give your shoulders somewhere to drop. They give older buyers something solid to hold while sitting down and standing up. They steady your arms for the welds, the cuts, and the work where your hands actually matter.
Now compatible with EZ-Lift chairs along with all Quick Height and Acme Rod models. Adjustable height, width, and pad angle dial in the fit to your build, your bench, and the work.
- Fits: All Robust Steel Max & Elevated Steel Max models

Feel product is very well built. It's a tad spendy. Would be great to see a little better discount for buying more products as you as to the accessories of your chair. All in all a nice product.
Perfect function
Excellent quality
Love them
Th e armrest is a terrific addition to what already was the best shop chair I have ever had. The chair was very comfortable before adding the armrest, it is even better now. I do have one minor problem that I will have to correct. The pads keep coming loose and sloppy around. I have to retighten the mount screws. I will likely add a drop of blue threadlocker to each screw. That is my only complaint and while it is annoying it doesn't keep me from loving the armrest. I would readily buy it again.
Easy to assemble, really rugged construction but a stylish look. Started with the basic elevated with ez lift, and a few days later decided I wanted to add arm rest, big boy seat and articulating back rest. Very straight forward assembly.
The chairs are awesome. That’s the pro. The con is this; You have apparently redesigned the chair arms and assembly. However, I bought my 1st chair maybe 2 years ago. I decided to add the arms as an improvement to a great chair. This is where you stubbed your toe. I advised Vyper I already owned a chair and needed arms for it. You sent the arms promptly enough except they don’t fit the iteration of the chair I own. I spent considerable time to determine this and then called you guys. A major issue was the instructions for my original chair and arm assembly has been removed from your website. Your service guy was phenomenal in helping me confirm the issue and in getting the assembly that is designed to fit. All that said I then bought the correct arms kit and an additional chair with an arms kit. None of these nuisances changed the quality of the chair. These things happen when you change a design. Sooner or later it’s going to bite you. Lesson learned is to confirm ordered part will fit prior to shipment. I spent 40+ years in GE’s Power Transformer business as Manager of manufacturing and later as GM for EFACEC’s transformer manufacturing in the US. The hard lessons come not from being perfect but in how you resolve a problem!! You fixed the mixup quickly and as I’m awaiting the remainder of the order, accurately. You guys did a stellar job in addressing the problem!! Sorry to be long winded. Is a great product and I look forward to working on my Restomod cars using them.
The adjustable armrest finishes off this incredible chair, making it even more comfortable.
The viper chair is a great addition to our work shop. My father who doesn’t get around well can seat and use your chairs to help assist him in moving around the shop to help with jobs. He’s not afraid to turn over and they adjust to just the right height.
High quality, nuclear-hardened, max comfort work chair. Pricey, but worth it. You know you want to own this. ;-)
They hold my arms.
So I’ve purchased two Viper chairs and love them. But I recently had a health issue and lost my left leg. Iv been using a wheelchair to motor around in my shop but I couldn’t use my Viper stool because of balance. So I decided to purchase the adjustable arm rest that added stability when I transferred over. This Wednesday I’m getting my prosthetic which will definitely help with getting around for my detail shop. Thank you Viper for continuing to build amazing products.
I really love my chair.
Great add on to a great chair! I got the high rise this time. I added the armrest later. Easy (and fun!) to install. Suits me perfectly on this chair!
Amazing chair and super solid. It’s added a new tool to my shop allowing me to work comfortable.
the adjustable arms and padding are not user friendly. to have to remove 4 bolts in order to widen or shorten them out and in. the forearm padding thumb nuts are not user friendly and are hard on the fingers when loosening and tightening. very generic. I will never buy the product again or recommend it.
Emailed to recommend that repeat customers be offered a discount for upgrades and additional items and was pleased with a discount code for the armrest and wheel locks which make the chair so much handier to use. Thinking about the adjustable backrest as possible future purchase especially if my old backrest had trade-in value. Cheers, Myron
Got the arm rest option. It is a nice feature to have but it doesn't seem like I could ever get the thumbscrews tight enough to keep the top pads from sliding around when I grab them. Might try removing the large washers or adding a rubber washer as well to keep them in place.
I'm short one 01-06022 support piece. No, I didn't misplace it, there were only 4 in the box. I'd really like to place the remaining one, to insure even more stability! Great product! I would NOT recommend the adjustable back that I ordered. The standard back support looks a LOT more cool, than the adjustable kit pieces. I did not install the adjustable. Overall, I'm really happy with the product! Joe Savage joesavageatm@gmail.com 512-864-5453 4011 Malaga Drive, Georgetown, Texas 78628
You can see the old stool I was using. Everything about my Vyper stool is AWESOME! The stool the seat the arms, and the back. I spend most of my time at my job sitting at the computer CAD designing. This is a game changer for me! I can not express enough how AWESOME this is. I am 60 years old. I will never have to replace it. It will be here after I am gone. WHAT AN AWESOME STOOL!!!
A little disappointed in the pad quality, thickness and small size.
Love these arms. No offense but the chair was nice without them but very nice with them. Glad I got the shipping coverage because FedEx lost track of these for a couple of days. So, I received them after I had assembled the chair. Pretty easy rebuild and we are up and at ‘em. Wiping the last of my tears. Very happy and satisfied with the product and Vyper!
Solid unit. Well put together
Adds to the comfort of the chair. Easy to install.
Love it
While arm rests aren’t an absolute necessity for me, it’s a nice option when working for lots of hours.
This was an addition to my chair my family purchased for me at Christmas. I also purchased the adjustable back rest. The instructions were easy to follow but the lack of instructions for the back rest was disappointing. Being 80 years old computers and Q codes do not impress me. After some questions to my self chair is complete and enjoyable to work on my 1934 Ford.
Outstanding addition to the vyper arsenal
Easy to install and a nice touch
It was great addition to the seat easy to install looks great and makes the chair more comfortable to sit in i love it and i get a lot of compliments from my co workers.
Today my sidekick arrived l immediately installed it on my chair. It looks so good and it going to give me the space I need for spray can towels and tools. The sidekick is solid
Thanks
I really like the armrests feature. I have a handicap and it makes it much easier to get out of the chair
it is TOO expensive for what it is
An excellent addition
Awesome addition to a great product!
Great attachment for the chair.
Best shop chair I have ever owned looked up on web and found viper brought 1 liked it my wife sat in it she had to have 1 brought the 2nd elevated it was to high gave her mine needed the lower one brought 3 one. Now I have 3 viper chairs and I love 💕 all 3 thanks viper you got me for life oh yeah also brought the creeper love all viper products made in the USA!!!!
I like the functionality but I have to say installing was difficult because I wanted the armrest to be as close to the seat extensions as possible, which created resistance and getting the through bolts in for the armrest was very difficult. Also the thumb bolts for holding the armrest pad pads are too small to tighten adequately to lock the armrest in place. So they are always sliding around.
Frequently Asked Questions
Everything you need to know before you upgrade.
What accessories are available for Vyper chairs and stools?
The most-purchased Vyper accessories are the Adjustable Backrest, Adjustable Armrest, Big Boy, Tool Tray, and Sidekick. Each one solves a specific problem:
- Adjustable Backrest: Replaces the stock backrest with a 10° tilt and 4" of height adjustment, for buyers who want to dial in lumbar support exactly.
- Adjustable Armrest: A solid grip for sitting down and standing up, and most importantly, to improve posture / stability.
- Big Boy: Adds 7" of seat width, for larger frame buyers or anyone who wants more room and stability.
- Tool Tray: Bolts to the underside of the chair to hold sockets, loose bolts, and shop rags.
- Sidekick: Side-mounted attachment with cup holders, a tool holder, and storage for spray bottles, polishers, and shop towels.
All accessories are made in Green Bay, Wisconsin and ship with the same warranty and 30-day guarantee as the chairs themselves.
What's the difference between the Sidekick and the Tool Tray, and do I need both?
The Sidekick mounts on the side of the chair for what you're actively using (spray bottles, polishers, microfibers, a cold drink), while the Tool Tray bolts underneath for what you've already used or what might fall (loose bolts, dropped sockets, shop rags, small parts).
They're built to work together, not against each other. Detailers and fabricators who run the Complete Package (Robust Steel Max + Tool Tray + Sidekick) consistently say the two-accessory combo turns the chair into a real mobile workstation. Sidekick at hand for the polisher you're using right now, Tool Tray below for the spent microfibers and parts. If you can only pick one, the Tool Tray is the accessory most buyers later say they wish they'd added from day one.
Can I use the Big Boy and the Sidekick together on the same chair?
No. The Big Boy and the Sidekick cannot be installed on the same chair, they mount in the same location and you have to pick one. Our specialists at (920) 301-3822 can walk you through the right choice if you're not sure.
The decision is usually clean. If you're a larger-frame buyer (or an older buyer wanting more leverage when standing), get the Big Boy. If you're a detailer, fabricator, or anyone who works with supplies at the seat all day, get the Sidekick. The Adjustable Backrest, Adjustable Armrest, and Tool Tray all work with either choice, so you don't lose any other accessories by picking one over the other.
Is the Adjustable Backrest worth the upgrade over the stock backrest?
For most buyers, the stock backrest is built right and works exactly as designed. The Adjustable Backrest is the upgrade for the buyer who lives in the chair, taller height range, up to 10° of recline, and the ability to dial in the support position to your specific body and the way you actually work.
Roughly half of buyers add it during initial chair configuration. The other half buy it months later, after deciding they want to fine-tune the backrest position even further. Reviewers consistently describe it as the upgrade that turns the chair from "comfortable" into "I never want to get up." Compatible with the Robust Steel Max and Elevated Steel Max chairs, and pairs with either the Big Boy or the Sidekick.
Who should buy the Big Boy attachment?
The Big Boy adds 7" of additional seat width, built for two specific buyers: larger-frame customers (280 lbs and up, or anyone who finds the standard seat too narrow) and older buyers who want more leverage when sitting down and standing up.
Reviewers consistently call it a confidence upgrade. The wider seat means you don't have to perfectly center yourself when sitting, and the wider surface gives you something to push off when standing. It's the most-recommended upgrade in the Vyper review base for buyers in their 60s, 70s, and 80s. Available on all Vyper chairs except the Low-Pro and Robust Steel Sport. Cannot be combined with the Sidekick.
Can I add Vyper accessories to a chair I already own?
Yes. Every Vyper accessory is designed to bolt onto chairs already in your shop, you don't have to buy them at the same time as the chair. Roughly half of buyers add accessories during the initial chair configuration. The other half buy them weeks or months later, after deciding what they actually need.
The Tool Tray, Sidekick, Big Boy, Adjustable Backrest, and Adjustable Armrest all install with basic hand tools and ship with instructions and hardware included. If you bought your Vyper chair years ago, the accessories from today's lineup are still compatible with the standard chair models. Call (920) 301-3822 if you're not sure whether an accessory fits an older chair.
Which Vyper accessories work with the Low-Pro and Robust Steel Pro stools?
The Vyper Backrest add-on works on the Robust Steel Pro and the Low-Pro Backrest works on the Low Pro, for buyers who started with a stool form factor and decided they wanted lumbar support after the fact.
The Big Boy is not compatible with the Low-Pro, but is compatible with the Robust Steel Sport. The Tool Tray and Sidekick are designed primarily for the Robust Steel Max and Elevated Steel Max chair frames. For a stool-specific tool-holding solution, the Robust Steel Pro ships with a built-in stationary tool tray as a standard feature, no add-on required.
